Bootstrap 3 phone number validation

Does anybody know if it’s possible to validate a phone number (just to check if the value is an integer) in bootstrap v3?

It´s not a bootstrap thing. Take a look at this one:

<input type="number" name="quantity" min="1" max="5">
<input type="tel" name="usrtel">
